Description
The wrapped-type intermediate joint is a splicing product that restores the cable structure and function layer by layer through a tape-wrapping process. Each tape has professional electrical properties, and its self-adhesive and self-fusing nature enables rapid fusion between the tape and the cable, as well as between tape layers, greatly reducing the possibility of gaps during installation. The advantage of the wrapped-type joint lies in the composite winding of multiple tape layers, providing good waterproof and sealing performance, which ensures long-term reliable operation of the cable.
